Abstract

Pulmonary tuberculosis manifesting as a mass lesion, thus, mimicking a lung carcinoma is an unusual radiographic presentation of tuberculosis (TB). The common radiologic patterns and clinical presentations are well known and documented. We report two cases of pulmonary tuberculosis with a neoplastic appearance on chest imaging diagnosed histologically. A 21 – year old female with cough, weight loss, anorexia and an unremarkable physical examination. Chest radiography showed a right apical mass suggestive of lung cancer. Histology of the lesion revealed parenchymal pulmonary tuberculosis. A 49–year old male with left-sided chest pain, cough, anorexia, weight loss, mild pallor with an unremarkable chest examination. Chest imaging showed a left apical mass and mediastinal lymphadenopathy. Microscopic examination of the mass confirmed pulmonary tuberculosis. Pseudotumour pulmonary tuberculosis is a rare clinical entity that can lead to diagnostic challenges and must be considered in the differential diagnosis when mass lesions are seen on chest imaging, especially in TB endemic areas.
